Detailed Description

A combobox which implements a history like a unix shell. You can navigate through all the items by using the Up or Down arrows (configurable of course). Additionally, weighted completion is available. So you should load and save the completion list to preserve the weighting between sessions.

void  addToHistory ( const QString& item )

[slot]

Adds an item to the end of the history list and to the completion list. If maxCount() is reached, the first item of the list will be removed.

If the last inserted item is the same as item, it will not be inserted again.

If duplicatesEnabled() is false, any equal existing item will be removed before item is added.

Note: By using this method and not the Q and KComboBox insertItem() methods, you make sure that the combobox stays in sync with the completion. It would be annoying if completion would give an item not in the combobox, and vice versa.

void  clearHistory ()

void  cleared ()
